5.2. External Dial Switch Connection

Connecting external switches such as

footswitches permits them to perform the

same operation as the dial keys "7," "8,"

"9," and "C".

An electrical current of 1 mA flows through

each contact.

Note

The cable length from the external switch

should not exceed 3 m.

Connect a keyboard of

which circuit

configuration is as

shown in the figure.

An electrical current of

1 mA flows through

INSTALLATION MANUAL

MASTER STATION BOARD N-8031SB

1. GENERAL DESCRIPTION

The N-8031SB is a printed circuit board unit for the N-8031MS

Flush-Mount Hands-Free Master Station. You can make the

master station suitable for applications using the N-8031SB in

combination with the operation panel section to be prepared

separately.

3. SPECIFICATIONS

2. DIMENSIONAL DIAGRAM

Use the N-8000 software* to perform settings. Set up the same

items as performed to the N-8031MS since the N-8031SB is

handled as the N-8031MS on the software.

Key and status indicator operations are exactly the same as

those of the N-8031MS.

For settings, functions, and operations, read the descriptions

about the N-8031MS in the N-8000 Series instruction manual*.

* Included in the CD supplied with the N-8000EX/8010EX

Exchange.

4.1. Installation Precautions

• To prevent a malfunction or breakdown due to static electricity,

be sure to use a metal case or metal panel, and screw the board

at the indicated hole, so that the board is electrically conducted

to the case or panel.

4. MOUNTING TO A METAL CASE OR PANEL

• Cover the whole board with a case when installing.

4.2. Speaker and Microphone Installation

• To prevent acoustic feedback, attach the speaker and

microphone closely to the panel and position them at least 16 cm

away from each other's center as shown below.

• Speaker opening ratio should be 36% (Example: ø4 mm x 61

holes) as a guide.

• Keep the board from coming in contact with the speaker to avoid

short-circuit between them.

• Make a microphone opening with the microphone rubber's inside

diameter (ø4.5 mm), and position the microphone in the way

that its center comes to the opening center.

• Never install them as shown below. Doing so may cause the

speaker sound to enter the microphone.
